Research links soil nitrogen levels to corn yield and nitrogen losses

What exactly is the relationship between soil nitrogen, corn yield, and nitrogen loss? Most farmers would be forgiven for assuming a straightforward linear relationship: more nitrogen, more grain yield, and maybe, more loss. That’s the assumption many nitrogen management models are based on, but it turns out there’s very little published science to back up that assumption.


In arecent paperleveraging a multi-year dataset from 11 experimental plots and on-farm trials around the state, University of Illinois scientists definitively established the relationship between soil nitrogen at different growth stages and corn yield. The results provide more precise ways to manage nitrogen for grain yield while lowering nitrogen losses.

“Technology nowadays moves very fast. There’s a lot of modeling tools out there to help growers match nitrogen to crop needs, but very little published data showing the relationship,” says Giovani Preza-Fontes, doctoral researcher in the Department of Crop

Nitrogen dioxide halved but sulfur dioxide doubled — ScienceDaily

A University of Liverpool study of air pollution in the UK during the first 100 days of lockdown has revealed that whilst nitrogen oxide levels were cut by half, levels of sulphur dioxide increased by over 100%.

Researchers from the University’s School of Environmental Sciences analysed data from the Department for Environment, Food & Rural Affairs (DEFRA) air-quality sensors and UK Met Office stations to see how lockdown measures had affected levels of nitrogen dioxide, sulphur dioxide, particle matter (PM2.5) and ozone, and compare it to data from the past seven years.

The study revealed that during this period (from 23rd March to 13 June 2020) nitrogen dioxide (NO2) levels were cut by half which would relate to the reduction in vehicle emissions. More surprisingly, though, the analysis found that levels of sulphur dioxide (SO2), typically created by UK industry but in sharp decline, were more than double that of
